Is there any canon ways of achieving a Nullify Arcanum Field (as per Silent No Longer spell)?

At the moment I believe this is something that was designed to be used against PCs, not by PCs. I'm sure the VO know how to do it

Maybe Ymandragore too.

Though somewhat helpfully I tend to find that if I stick a sword ALL the way through something's spleen then they don't cast spells anymore. (or maybe with Tukufu shoot all three flintlocks in quick succession).

Ursula finds a similar effect when she hits with her Tralian Hammer.
